Definitions

  • the invention relates to a device for launching and hoisting up a lifeboat, pick-up boat, etc., and for picking up persons and objects floating in the water, which comprises two booms from which ropes extend to two elongated buoyancy means which are connected at a mutual distance and are connected with the ropes by the aid of spreader yokes, from which lines extend to the buoyancy means, and bottom members spanning the space between said buoyancy means and being in the water when the buoyancy means are afloat, said lines extending in guides on the buoyancy means and acting as guides of the buoyancy means when the latter are afloat, said lines being connected with the respective adjacent bottom members.
  • a device for launching and hoisting up a lifeboat, pick-up boat, etc. which comprises two booms from which ropes extend to elongated buoyancy means which are connected at a mutual distance and are connected with the ropes by spreader yokes from which lines extend to the buoyancy means.
  • the space between buoyancy means is spanned by bottom elements which are in the water when the buoyancy means are afloat.
  • the utilized booms are designed to be independent units, as known from conven ⁇ tional davit arrangements.
  • To stabilize the dock formed by the buoyancy means in the water a comparatively complicated and expensive arrangement of hydraulic arms extending down into the water from supporting means placed along the ship's side is used.
  • a weight lowered into the water is known to stabilize a vertically suspended line, and it is also known that said weight may be designed as a bottom member spanning a pick-up dock.
  • a device as mentioned above is proposed according to the invention, which is characterized by the fact that said two booms are combined into a fork- shaped swingcrane-boom unit, that the booms are telescopic, and that ropes extend from the fixed boom sections to spreader yoke for one buoyancy means, whereas ropes exten from the extendable boom sections to a spreader yoke for th other buoyancy means.
  • the davit-arrangement is, thus, abandoned and the advantages achievable by the aid of swing crane are in stead utilized.
  • the doc formed by buoyancy means may be hoisted up from the water an may, by the aid of the swing crane, be slewed quite distance inwards on deck, e.g. onto the relatively protecte working deck on a supply vessel.
  • Such a possibility o hoisting the dock with its content upward and inward i essential in connection with picking up hyperbaric lifeboats, because necessary equipment and assistance may, thus, reac the lifeboat.
  • Each spreader yoke is connected with one buoyancy means.
  • Each, spreader yoke is connected with both arms or booms o the two-armed swing crane. Due to the fact that the booms ar telescopic the position of outermost buoyancy means relativ to the swing crane may be adjusted relative to the othe buoyancy means by retraction/extension of the telescopi outer boom sections. This provides for a possibility o achieving an especially advantageous mutual adjustment o the buoyancy means, so that the dock formed by the buoyanc means may be provided with an enlarged lead-in opening b arranging the buoyancy means in a mutually divergen position. This is achieved by extending one telescopic boo more than the other one.
  • said boom uni comprises a rigid fork stem which is slewable about horizontal axis on the slew ring of the crane, said two for members being telescopic. That means that only the outermos portion of the swing crane is fork shaped or two-armed.
  • Thi embodiment is advantageous in that that there is one singl fork stem to be slewed and raised and lowered in stead of tw booms outside the slewing ring.
  • the fork elements are, advantageously, placed to enclose a obtuse angle with the fork stem. In the normal workin position of the fork stem the fork members will then advantageously, extend horizontally outwards, i.e. fairly i parallel with the water surface. In this manner the fre length of both outer ropes is reduced.
  • a control line may, advantageously, exten from each end area of the buoyancy means closest to the cran to a suitable winch.
  • a three-armed line-fork may, advantageously, extend from eac rope to the corresponding spreader yoke.
  • Such a design wil provide the necessary stable suspension of spreader yokes an associated buoyancy means.
  • the elongated buoyancy means may, advantageously, comprise number of sequencially joined floats.
  • Spreader yokes wil provide the necessary stability, at the same time as the doc will show desired flexibility in the water.
  • the dock may be open at one or both ends, as required. On dock end may be closed by the aid of floats of the same kin as those used for the elongated buoyancy means.
  • bottom members connect the lines beneat buoyancy means and act as spreader members.
  • An especiall suitable design of the bottom members which is of Indepen dent inventive value, comprises bottom members in the shap of slings having the same length of spring steel attached t them, which are baked into a flexible material protectin both materials.
  • Such a bottom member would be sufficientl rigid to provide desired spreading and will, at the sam time, at least to some degree, adapt to the shape of th object inside the dock and support said object.
  • a net may, advantageously, extend in manner known per se, which is of special importance whe relatively small objects, e.g. persons, are picked up fro the water.
  • the swing crane is preferably provided with a contact face which the dock may be made to contact Said control lines may advantageously be used to this end.
  • Figure 1 shows an elevation of the device according to the invention, as seen along a ship's side
  • Figure 2 is a plan view of the two-armed swingcrane shown in Figure 1,

  • slewing ring 7 unit 4 By the aid of slewing ring 7 unit 4 is, thus, in a manner known per se mounted to be slewable about a vertical axis of crane foundation 3.
  • a fork-shaped boom unit 8 is mounted to be slewable about a horizontal axis 9 in tower 5 and may be slewed up and down 0 about journal 9 by tbe aid of a hydraulic working cylinder 10.
  • boom unit 8 The fork-shaped design of boom unit 8 will appear clearly from Figure 2, showing the swing crane from above.
  • Boom unit 5 8 thus, comprises a rigid fork stem 11 and and a fork which extends at an obtuse angle relative to stem 11 and comprises two telescopic boom sections or fork members 12 and 13.
  • Each fork member is comprised of a firm section 14 and 15, respectively, and a telescopic or extendable boom section 16 o and 17, respectively.
  • the swing crane totally comprises four ropes extending from winches 18.
